Hart (Shenghei Yamaguchi) is a Tyrannosaurus Rex raised by herbivorous dinosaurs. In fact, as early as when it broke out of its shell, the leader of the herbivorous dinosaur ordered Hart's mother (Tomoshi Harada) to abandon it, but his mother eventually secretly raised it. As he grew older, Hart, who ate only wild fruit every day, was so hungry that he could not resist the drive of instinct and began his brutal carnivorous life. However, due to the influence of his mother, there is always a kind heart in the depths of Hart's heart. One day, he occasionally met a baby herbivorous dinosaur with a broken shell. Hart was mistaken for a "father" by the baby dinosaur, and named the little dinosaur "delicious". From then on, another strange relationship between father and son began. However, with the deterioration of the living environment, the survival of dinosaurs has suffered unprecedented destruction, Hart and his relatives can finally withstand the test.
